Making or receiving a call during a power failure
(Simplified power failure voice call)
In the event of a power failure, you can make or receive
calls from the main unit or the portable handset by using
the battery in the main unit.
You cannot use other functions such as fax, copy or
answering device.
When you first purchase this product, you can make
or receive calls only from the main unit. If you wish to
make or receive calls from the portable handset as well,
it is necessary to make settings (see below).
To make provision for a power failure, be sure to insert
the battery in the main unit. (See “Inserting the battery
into the main unit” on page 4.)
When you insert the battery, it will start to be charged,
enabling it to function as a power source in the event of
a power failure.
When you carry out a simplified power failure voice call
operation, the display on the main unit will light up for
30 seconds.
During a power failure, the display and lamps will go
out. If the display does not light up when you pick up the
handset, it means that the battery has completely run
down. (Unless you carry out an pushbutton operation,
the display will go out after about 30 seconds.)

After a power failure has occurred, the usable period will be reduced until the battery is fully recharged again.
When the battery inside the main unit runs down, you cannot make a voice call from the portable handset even if there
is a charge remaining in the battery inside the portable handset. Also, if the charge in the battery inside the portable
handset is low, the above period will be reduced further.
